Abstract
A method and system for injecting a deterministic fault into storage shelves in a storage subsystem. The method comprises injecting a known fault condition on demand into a hardware component in a storage shelf to cause a failure of the storage shelf. The hardware component incorporates a circuit that is configurable to select between a normal operating condition and a faulty condition of the hardware component. The method further comprises verifying that a reported failure is consistent with the known fault condition.
